This works fairly well if used properly. Squirt it on with a gun and smudge over the sealant with a brush, leave for a couple of hours and most of the sealant comes away quite easily. If you have heavily applied sealant you might have to have a couple of goes at it or do the remainder with a...

Aaaah! Then I could have run 22mm up to the small gap, then had a short stretch of 15mm through the gap, into more 22mm beyond the gap. That way I would have solved the problem of getting through the gap and got better flow. Is that what you are saying? If I am happy with the pressure I get...

BTW, I also wonder at the amount of expensively heated water that gets left in these pipes to go cold.

I understand that 22mm would be preferable. But there isn't room for it unless I make detours, start hacking flooring about. So 15mm it is. I've managed it with only 3 right angles and a bit of pipe bending over the 4.5 metre run (<4 vertical) between pump and shower head. I have yet to put the...

I have 22mm hot and cold supplies. I see 22mm recommendations all over the fora but, having looked closely at the pump and flexible connectors, the channels through which the water flows is only about 10mm. This is also the case with inserts for plastic pipe, which I am not using. This leads me...

run - 4.5 mtrs cistern - 6 mtrs above hot tank head-cold cistern - 1 mtr route - pump on grnd flr, up to next flr, 4.5 mtrs with 4 elbows. type - Aqualisa classic aquavalve I've bought 15mm copper and the Grundfos Nile...

Thanks for the reply. That's good. Now I'm wondering whether to use plastic or copper pipe. I'm not capable of soldering anything so I think plastic with short copper runs at each end is probably the same as far as water flow/restriction is concerned - there will be four right angle turns...

My hot tank and pump are on the floor below the shower with the cold tank above the shower. I can't work out whether 22mm or 15mm pipework makes much difference if you are only running the one shower off a 1.5 Bar pump. I have 22mm hot and cold pipes feeding the pump. BUT, they have a...

I am in a similar position, except my hot tank and pump are on the floor below the shower with the cold tank above the shower. I wondered how you got on with the 15mm pipework in the wall. Did you get plenty of pressure? I can't work out whether 22mm or 15mm makes much difference if you are only...
